S-92311A576 5/16"-18 x 3/8" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction for long-lasting performance in harsh environments
• Exceptional holding power achieved through Class 3A thread fit precision and Rockwell B80 hardness
• Secure, flush installation enabled by headless design and hex socket drive for streamlined assemblies
• Enhanced grip and alignment provided by cup tip design for reliable component positioning
• Optimal torque transmission through 5/32" hex drive socket, reducing tool slippage
• Industry-standard compatibility with UNC coarse threads (5/16"-18) for broad application use
• Regulatory compliance assurance meeting ASME B18.3 specifications and environmental standards

Professional Applications & Engineering Value

This 5/16"-18 UNC set screw delivers critical engineering solutions where vibration resistance and permanent positioning are paramount. The 18-8 Stainless Steel construction provides excellent corrosion resistance for machinery operating in humid or chemical environments, while the Class 3A thread fit ensures precise engagement that maintains clamping force under dynamic loads. The hex socket drive (5/32") allows for high-torque installation in confined spaces, and the cup tip design creates concentrated contact pressure that prevents component shifting. Ideal for securing gears, pulleys, and collars on shafts in manufacturing, automotive, and industrial equipment applications where reliability cannot be compromised.
